MARKING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 753,435, dated March 1,1904.

Application filed August 6, 1903.

Toa/ZZ whom it 11i/Ly concern.

Be it known that I, EDWIN M. SCIIANTZ, a citizen of the United States,residing at Zimmerman, Green county, State of Ohio, have inventedcertain new and useful Improvements in Marking-Machines; and I dodeclare the following to be a clear, full, and exact descriptionthereof, attention being called to the accompanying drawings, with thereference characters marked thereon, which form also a part of thisspecification.

This invention relates t improvements in marking-machines of the kinddescribed in a patent issued to me on July 28, 1903, and which machinesare used to mark oif by lines pieces which are to be cut from a largerpiece, said marked-orf lines indicating the lines on which this latteris to be subsequently cut. The machine shows at the same time thesuperficial dimensions-that is, length and width of the surface somarked o for subsequent cutting.

While these machines may be used on most any kind of material of limitedthickness,

they are exceedingly well adapted for use in connection with lumber,theinvention being accordingly described, and larger pieces of which,like boards, planks, &c., are to be cut up in smaller pieces, whichlatter may be socalled mill or i dimension stuff.

The patented machine as well as this present device consist, first, of amember called a marking-guide and which serves to guide a pencil, pieceof chalk, or other suitable marking implement while the same,held in thehand, is moved over the surface to be marked off. "In connectiontherewith is used anv indicating measuring device operatively connectedtothe marking-guide in a manner that any change of this latter from oneposition to another is immediately shown in certain selected scaleunits-as inches, for instance-thereby, while showing the distancebetween the markinglines as run bythe marking-guide, also indicating thecorresponding size of the particular 'piece to be marked off forsubsequent cutting.

A leading. feature of the machine described in the patent is that themeasuring device while showing the sizes of the pieces shows at the sametime whether pieces of such size `are Serial No. 168,459. (No model.)

wanted. The means whereby this eect is obtained are adjustable inarrangement, so that the machine may be arranged accordingly and beforeuse to set it to various sizes which are wanted and to show them. Thus,for instance, in mill-work where numbers of certain-sized pieces have tobe turned out the machineV is arranged and set accordingly before workon a certain order is started, after which the marking-guide whilemanipulated causes the measuring device to show the width of the piecesmarked, the measuring device also showing in addition and at the same`time what pieces and of certain` sizes are wanted. Thus, for instance,pieces of various lengths may be wanted all of the same width. In such acase the operator while having the required sizes before his eyes, asindicated by the measuring device, may where the pieces are alsorequired to be clear of defects arrange the running of the markinglineswith respect to. existing defectslike knot-holes, for instance-to avoidthese and at the same time obtain pieces which may be made use of, thusentailing very little or no waste. For instance, he may mark out asmaller piece where by reason of existing defects he cannot obtain alargerone, the measuring device showing him how to arrange the size ofsuch smaller piece, so it can be made use of. Y Y

This present machine may be used in the same manner, except that themeans for attaining the desired results have been changed and improved.A different measuring device is used, and the means which indicate widthand show what various sizes are wanted have also been changed andimproved.

The invention consists, therefore, of these changes and improvements asthey are hereinafter described'and claimed and as they, together withtheir operating parts and construction, are illustrated in theaccompanying three sheetsof drawings, in which- Figure 1 shows a topview of the improved machine with all parts in their normalposition anda piece of lumber all ready for starting operation. Fig. 2 in a similarview shows operations started. Fig. 3 is a front view of the machine.Fig. 4; is the upper part of a'longi- 'IOO Vtudinal section taken backof and parallel to the preceding front view. Fig. 5 is a verticalcross-section of the machine. Fig. 6 is an end view of the same. Figs.7, 8, and 9 are enlarged detailed views which will be referred to in thefollowing description, after which they will be fully understood. Fig.10 in a view similar to Fig. 8 shows a modified construction of theindicating means. Figs. 1l and 12 in views similar to Figs. 8 and 9 orparts of 5 and 2, the first being a cross-section, the other a top view,show -the indicating means electrically operated. Fig. 13 shows a frontview of the lamp-carrier.

The lumber 15, to be marked for subsequent cutting up, rests upon asuitable support constituted, preferably, by rollers 16, mounted in aframe 17, and which facilitate the manipulation of the lumber and permitit to be easily moved along by being slid over said rollers.

18vis the marking-guide-that is, thatdevice which guides the hand whilerunning those lines which divide the board longitudinally. Pencil orchalk may be used or an implement, as shown in Fig. 7, having a handle19, carrying a serrated roller 21, like a tracingwheel, and aguide-roller 22, fitted into a groove 23 of the marking-guide. Thismarking-guide is carried by two arms 24 24, extending rearwardly fromits ends, and which arms are supported in frame-arms 25 25, the supportbeing in a manner which permits said arms 24 to move back and forth forthe purpose of permitting placing of the marking-guide in position abovethe wood wherever a particular line is to be run. This support is,further, such that 4these arms during their movement are guided in amanner that the' various adjusted positions of the marking-guide,respectively, the lines run thereby, are all parallel to each other. Forsuchfpurpose grooves or shoulders may be provided in frame-arms 25,acting as guideways 26, on which arms 24 of the marking-guide areguided.

Supported below the marking-guide, preferably, also, on arms 25 and in amanner to be free for a similar guided movement, there is a measuringdevice 27 showing widths and having also rearwardlyextending arms 28 forguidingv and supporting it on arms 25. At the beginning the parts are ina normal or Izero position, as shown in Figs. 1 and 5, front edge 27a ofthe measuring device, the inner edge 18 of the marking-guide, and thefront edge 15a of the board being all alined in juxtaposition. The boardis advanced from right to left along stops 29, which dene the positionabove referred to, and, as shown in Fig. 2, it has nearly reached itsend.

The operation ofthe marking and measuring devices is, however, the sameas to any portion of the board, which is over the table and below themat the time. Thus, for instance, if a piece is wanted of a certain widthor of a certain width and also clear of defects or knot-holesmarking-guide 18 is moved out, as shown in Fig. 1 in dotted lines, andin which position it does not include any knotholes on the board shown.The width is assumed to be about eight inches and a markingline c wouldbe run. (See Fig. 2.) Before running the next line members 18 and 27must come again to a Zero position on line c, for which purpose member27 is pulled out to meet line c, as shown in Fig. 2, and where it alsomeets member 18 in its advanced position, as the same is shown in dottedlines in Figs. 1 and 2. For running the next line markingguide 18 isadvanced again-that is, moved away from member 27 and as shown in Fig.2. The width of the pieces are shown by the distance between edges 27and 18EL and may be indicated by the position of front edge 27u of themeasuring device with reference to certain graduations which may be onone of the arms 24, preferably the left one. Fig. 2 shows best thismanner of reading. Lengths may be shown by graduations or notches eitheron edge 18a lor 27, or both. This measurement starts from the inner edgeof left arm 24. (See position of board in Fig. 1.) Cross-lines or linesdefining ends of the pieces marked being only of limited lengths may berun free hand, or an additional markingguide 31 is used, which ishingedly mounted on a rod 32, on which it may be laterally adjusted tothe proper position. This rod may be supported between arms 25 orbetween arms 24 and move with them, as shown, the connection in eithercase to either set of arms being the'same. Guide 31 has a projection 33on the under side of its free end whereby it may be temporarily held inposition while a line is run, said projection dropping into one of anumber of notches 34 in the edge of marking-guide 18 and graduated tocorrespond to the scale on edge 27 a. Marking-guide 18 and measuringdevice 27 may be locked together if, for instance, a large number ofpieces would have to be marked which are all of equal width and also ofequal or various lengths, so that for adjustment to a new line the twocan be moved at once intstead of first moving member 27 to the 4Zeroposition or to the previously-run line and then marking-guide 18 to thenew position. This is done by a pin 35, mounted in a lug 36 on member27, and which pin may be pushed in any of a number of openings 37 on theinner side of arm 24 and spaced to correspond to the graduations on saidarm. (See also Fig. 7.) l/Vhen so locked together, it is only' necessaryto move edge 27EL to the Zero position or to the pre- Viously-run line,the marking edge 18*L being found then at once in its proper position.

When clear pieces free of defects and at the same time of xed sizes aredesired, the running of the marking-lines isgoverned simultaneously bythese two controlling circum- TOO IIO

' quarter inches may also be shown.

. D Y V v stances. Thus, for instance, when a larger (wider or longer)piece cannot be marked out on account of an existing defect theparticular clear area may be utilized to mark out on it a smaller piece,thus obviating waste. To show the operator at once whether he can soutilize a particular stretch of board and without having iirst toconsult his order-list tosee whether such a smaller piece is wanted andcould be made use of, I provide a dimensionindicating device which showshim at once whether he can use such stretches or what part of it. Hewill then place his marking-guide in position to clear any defects andalso at the same time watch his dimension-indicator, which will show himall the various sizes of pieces wanted close to the position set and thenext available size he will make use of. This device consists, rst, ofwhatI call the -size board 38, so connected and supported as to movewith the measuring device 27, it being connected to arms 28 thereof. Itconsists, substantially, of a metallic plate and should be of sulicientthickness and rigidity to carry free between the frame-arms 25 25 unlessi n termediate supports or a continuous shelf are provided between thesearms and below said plate, in which case its thickness and weight may beaccordingly limited. This plate is provided with removable projections,preferably in shape of plugs 39, to be inserted in openings 4l. Theseopenings are arranged in rows lengthwise and crosswise on the board, andthey are spaced in these rows to correspond to the graduations on arm24, showing width of pieces, and also to correspond to the graduationson scale 27 which shows lengths. While all these graduations and scalesand also the spaced openings 41 are only shown for every three inches toobtain a clear drawing, they should in practice appear one at least forevery inch, and, if preferable, the half and At the beginning of a dayswork or when a certain order is to be turned out this board is studdedwith plugs 39 in proper position. For instance, if pieces are wanted sixinches wide and three feet long a plug is placed at the intersection ofthese graduations, such plug then indicating at the same time length andwidth. If several lengths are wanted at the same width, additional plugsare placed in the same longitudinal line, &c. In conjunction with thissize-board operates the indicator proper, the same consisting of acarrier 42, connected so as to move with marking-guide 1,8, it beingattached to the rear ends of arms 24 thereof, so that when themarking-guide is moved said carrier is also caused to move, it passingover the size-board. This carrier is provided with devices spaced so asto correspond to the graduations showing lengths on scale 27 a, so thatthese devices depending suflciently they will move in a path nwhere theywill encounter plugs 39 wherever they may be. This contact I usetovoperate indicating-signals which are visible to the operator and showhim, whenever one of them acts, that he now has moved his marking-guidein a certain posi- Ytion which defines a certain dimension of a boardand which board is wanted in his order. The width is given at once 'bymarkingguide 18, which he simply leaves where it was at the moment itoperated the indicating-signal, unless a defect in the wood shouldinterfere and prevent him from getting a clear piece, in which case heagain moves the marking-guide to the next available size. The length isalsogiven by theposition, laterally considered, of .the particularsignal actuated by the particular plug beneath, and according to itpheadjusts the other marking-guide 31, provided, however, that no defectsin the wood interfere. Thus, again referring to Figs. 1 and 2, it willbe noted by plugs 39, inserted on the size-board, that pieces six incheswide and three feet long and of same widthand four feet long are wanted.The marking-guide when arriving in a position six inches from edge 27aLwill'therefore cause two signals to operate, one representing a piecesix inches by three feet and the other six inches by four feet. Onlooking at his lumber the operator observes that he cannot obtain thelonger piece free of knotLhole-s. (See Fig. 2.) He therefore placesguide 31 as shown in said figure and marks out the shorter, but clearpiece. The particular means for operating these signals may bemechanicalaa for instance, they may consist of little angular pieces 43,pivotally supported on carrier 42, and the lower members of whichdepend, so as to encounter plugs 39. This causes the other members torise up, las shown in dotted lines in Fig. 8, thereby becoming visibleto the operator, or they may consist of vertically-operating means likepins 40. (Shown in Fig. 10.) They would also allow a closer subdivision.They may also be operated electrically by means of small incandescentlamps arranged and used on the principle of the moderntelephone-switchboard. There would be a lamp 44 for each size, as nowshown by the devices on carrier 42, andwhich lamps would 4be carried ina bridge 45, supported either stationary between arms 25 or between arms24, so as to move with the markingeguide and carrier and as shown inFigs. l1 and 12. The carrier would of course not have the signal-levers,their place being taken byelectrical contact-pieces 46 in shape ofyielding springs, one for each lamp. The entire size-board 38 wouldserve as a part of the current-carrier, so that whenever one of themetallic plugs would come in contact with oneof these pieces theparticular lamp would light up.

The lamps may be arranged as shown in full size in Fig. 13, a diifere'ntcolor being used for the inches, halves, and quarters.-

.The wires 47 may rpass directly each over to IOO its respective lamp,as shown, or they may be bunched first on carrier 42, then carried overas a rope to the lamp-bridge 45 and distributed again. Going out theyare preferably bunched or otherwise consolidated, as shown at 48.Suitable supports may be provided to hold up the necessary surplus o'fwire which is needed to compensate for the movement of the parts. 49 isthe wire to the size-board, and 51 is the outgoing wire.

It may sometimes be necessary to run lines not parallel to the edges ofthe board, which requires that this latter be free to be shiftedunimpeded by any stops. Stops 29 are for such purpose caused to dropbelow the surface of the rollers which support the lumber. To permitthis, stops 29 are pivotally supported on a rod 52 and connected to eachother by another rod 53, so as to move as one. trip-lever 54, suitablyengaged-as, for instance, to one of the tie-rods 55 of themachine-frame-holds stops 29 in their normal position. By releasing saidtrip-lever, which may be done with the foot, they drop below therollers, as shown in dotted lines in Fig. 5.

When changing from one thickness of lumber to another, the meanssupporting the same should be vertically adjustable. This may be done byvarious means-for instance, as shown in my prior patent or as shownhere.

The roller-frame 17 is provided .with two brackets 56, embodying each anut 57. A screw 58 is fitted to each of these brackets and supported bya bearing 59, whereby it is also held against longitudinal movement. Bytwo sets of bevel gear-wheels 61 these two screws are simultaneouslyrotated, and according to the direction of rotation the rollerframe withthe lumber on it is either raised or lowered. For the purpose of suchsimultaneous rotation one wheel of each set is mounted on a commonshaft, rod 52 serving as such, and is provided with a crank-handle 62for rotation.

The openspace shown between the measuring device 27 and size-boardBS isnot necessary, and arms l28 might be omitted,.since the two former moveand operate as one, the measuring device being practically the frontedge of the size-board. I prefer, however, the space shown between them,as permitting a more extended observation of the lumber.

Considering the many possible combinations as to sizes required andlocation of defects, it is of course not possible to describe all thepossible uses and necessary manipulations of the machine; but these willreadily suggest themselves to the practical lumberworker.

Having described my invention, I claim as new- 1. In a marking-machine,the combination of a support for the material, a marking device or guideand a device arranged parallel thereto. and operating 1n conjunctionwith it to showwidths, this operation being? by adjustment of one of thetwo devices last mentioned with reference to the other and parallel toeach other, each being adjustable, the adjustment of both being over thesurface of the material and in a plane also parallel to it and to eachother'.
